June 10 2014 (version 2.8.0)
V2.7 is a major upgrade that adds support for up to 7.1-channel surround and the ability to analyze audio and the audio parts of video files offline for their BS.1770-3 Integrated Loudness, EBU R 128 LRA, highest
reconstructed peak level, and number of reconstructed peaks above0 dBfs. It will graph the BS.1770-3 Integrated Loudness and peak swingsof the CBS Loudness Meter as a function of time, and can display a
histogram of the BS.1770-3 Integrated Loudness. At this writing, v2.7 isonly available for Windows Vista/7/8. It is not compatible with Windows XP and earlier. We will continue to make v2.0 available for Mac and
Windows XP users.
New features in V2.0 include full support for BS.1770-3 and EBU R 128,logging, manual mode (start/stop), and oversampled peak measurement that accurately indicates the peak level of the audio after D/A conversion.
In addition to a Windows® version, a Mac version is now available.

This looks nice, but I couldn't figure out how to get it to work. It wasn't a VST I could put on the master bus, unless that's changed.

It runs as a standalone using your audio card, not as a plugin in you daw.
If you can't get the meters to work you might want try or keep it for it's Analysis feature.
There's many R128 / EBU meters available now & as R128 becomes more the norm you'll see more.
I also suggested a feature to Jeron at Toneboosters which I hope he'll work on for a future product.
